i would like to ask you few question that i cant understand on F5 article.
i will upgrade one of my customer VE devices from 188.8.131.52 to 16.1.0, they are using DNS module.
and i prepare all the settings f5 recommend such as ; taking archive from both devices, re-activate their license, install the proper software, verify the md5 with .iso but i saw and article regarding bigip dns software update.
Hello, This is why you stop the the "Synchonize" before the F5 DNS upgrade. Just upgrade your devices and then again enable the dns sync. Also if you have LTM devices better to upgrade them first as written:
Also you may after the DNS HA upgrade to upgrade the big3d of any other DNS systems (if you have more than the two DNS devices that are active/standby) that are still the older version in the same DNS sync group:
